SHAFT FOR WINDINGPAPER.

SPEGIFIGATIONforming part of Letters Patent No. 508,801, dated November14, 1893. Application filed October 81, 1892- Serial No. 450,419. (Nomodel.)

Saratoga Springs, in the county of Saratoga. and State of New York, haveinvented an Improvement in Shafts for Winding Paper, .of which thefollowing is a specification.

Paper as it is delivered at the mill in the form of a web is rolled upso as to be adapted to transportation and use, especially in printingpresses, and in order to secure theadvancing end of the sheet or webto'the-rotating shaft it has heretofore been usual to employ a shaftthat is grooved at one side, and into this groove is laid around metalrod to press'the paper into such groove; hence when the paper is woundinto the form of a roll the opening therein isnotcircular and to removethe shaft from the roll of paperthe rod is drawn out endwise, usually byhammering upon an L-shaped projection, and this loosens the papersufficiently to allow the shaft to be drawn out, but the irregular shapeof the hole prevents the roll from running regularly and truly whenplaced upon the shaft previous to unwinding such roll, and considerableloss of paper arises in consequence of the irregular condition of theinner end of the paper, because in drawing off the paper the irregularshape of the same at the opening produces a slackness at one time and anunusual tension at another.

Our present invention is made with reference to employing a perfectlycylindrical shaft and holding the paper thereon so that the roll iswound up with uniformity and the opening in the paper is circular whenthe shaft is withdrawn.

In the drawings, Figure 1 is a side View representing the improved paperwinding roll. Fig. 2 is a cross section at the line at, Fig. 3 is across section at the line y, 'y, and Fig. 4 is an elevation partially insection of one end of the roll.

. The shaft A is provided usually with end bearings or journals Aadapted to be received into suitable boxes or bearings, and there is awedge-shaped segment B at one side of this shaft. The convex surface ofthis segment coincides with the cylindrical surface of the other portionof theroll, but

the line of separation being at an inclination to the axis of the rollallows for the segment being larger at one end than the other, and inthe larger end of the segment B is an elongated mortise 2, and there isa recess in the shaft itself at 3, so that the end of a bar 0 may beinserted through the mortise 2'into the recess 3, and suchbar can beused as a lever for starting the wedge, as illustrated by when desired,as shown by dotted lines in said Fig. 4. It is advantageous to employthe collars D D around the shaft, and these collars are provided withset screws 5, so that y they can be held in position after being set upto each edge of the web of paper. It is now to be understood that thescrews are loosened and the collars D D slipped away from each other andthe end of the web or sheet of paper is laid upon the flat side of theroll A and then the wedge segment B is applied upon the surface of thepaper and the collars D D are slipped over the wedge and set up to theedges of the paper and clamped to hold the wedge and the windingoperation is thereafter performed by the rotation of the roll A asusual, and when the roll of paper has been wound up of the desired sizethe wedge B is withdrawn by the action of the lever O, as beforementioned, the collars being loosened and removed, so that after thewedge has been withdrawn from within the roll of paper the shaft can betaken out, it being understood that the withdrawal ofthe wedge loosensthe parts sufficiently so that the paper will not bind around the shaftA itself.

The length of thewinding roll or shaft will vary according to the widthof the paper.

We claim as ourinvention 1. The roll for winding paper formed of a shaftwith a wedge-shaped segment separated in a plane on an inclination tothe axis in combination with collars movable longitudinally on the roll,and means for applying a subsequently lever between the two parts of theroll to I there being an opening in the wedge and a start the wedge forwithdrawing the same recess in the roll for the receptionof a leversubstantially as specified. to move the Wedge, substantially as setforth. 2.
